Description

  The present invention relates to a light bulb, and more particularly, to a light bulb having a light emitting diode as a light source and a light emission direction substantially close to all directions.

  Light emitting diodes (LEDs) have been extended to various lighting fields due to factors such as power saving, no heat generation, and long life. However, the light emitting diodes are usually limited to a certain range due to structural factors such as the package, and as a result, many of the light emitting diodes that are currently being used are used in projection-type applications such as , Flashlights, vehicle lights, outdoor lights, etc. In contrast, incandescent light bulbs that are most commonly used in homes currently emit light using the thermal effect of filaments, and the direction of light emission is omnidirectional. Therefore, in the lighting of a house, when the light emitting diode is used to replace the conventional filament, it is necessary to solve the locality problem of the emitting direction of the light emitting diode.

The light bulb provided by the present invention includes a lamp that can transmit at least one light. One end of the lamp body is provided with an end body that can be screwed into a conventional incandescent bulb socket to be electrically connected. The light bulb further includes at least one lamp panel and support column. At the periphery of each lamp panel, a plurality of light emitting diodes facing each other are provided at intervals. The support column extends from the end body into the lamp body, and connects the lampboards at appropriate intervals.
Each lampboard has at least one circuit and is operated by supplying electricity to the light emitting diodes thereon. The support column also has a conductive mechanism and extends and connects the electrical connections of the ends to the circuit of each lamp panel.

The present invention has the following features.
(1) a translucent lamp,
Provided at one end of the lamp body, provided with external threads and electrical contacts, can be screwed into the bulb socket, and the end body to which the bulb socket is electrically connected;
A support column extending from the end body into the lamp body;
A light emitting diode disposed within the lamp body and connected to the support pillar, the periphery of the light emitting diodes being spaced apart from each other and having at least one circuit, the light emitting diode; A power panel to supply electricity
Including at least
An omnidirectional light bulb using a light emitting diode as a light source, wherein the support pillar has a conductive mechanism, and the conductive mechanism connects the electrical connection of the end body to the circuit of each lamp panel.
(2) An omnidirectional light bulb using the light emitting diode as described in (1), which has at least two lamp panels.
(3) An omnidirectional light bulb using light emitting diodes as described in (2), in which the light emitting diodes of adjacent lamps are alternately arranged.

The present invention provides a light bulb having a light emitting diode as a light source and a light source emitting direction substantially close to all directions.

It is side explanatory drawing of the Example of the omnidirectional light bulb which uses the light emitting diode of this invention as a light source. It is an upper surface expanded explanatory view of the lamp board of the omnidirectional light bulb which uses the light emitting diode of this invention as a light source. It is side explanatory drawing of another Example of the omnidirectional which uses the light emitting diode of this invention as a light source.

  The above and other objects and advantages of the present invention are described below in conjunction with the drawings and detailed description of the embodiments. However, the drawings are provided to explain the spirit of the present invention, and are not considered as definitions of the category of the present invention.

  As shown in FIG. 1a, the light bulb provided by the present invention includes a lamp body 10 capable of transmitting at least one light. The lamp body 10 is hollow, and the outer shape thereof may be a spherical shape of a conventional incandescent light bulb or an egg shape as shown in the figure or other suitable shape.

  One end of the lamp body 10 has a thread 21 and is provided with an end body 20 of a light bulb socket (not shown) into which a conventional incandescent light bulb can be screwed. The end body 20 typically has two electrical contacts (not shown, usually one thread 21 itself and the other provided at the bottom of the end body 20) for the voltage provided by the bulb socket. Connect with two poles. The end body 20 can be provided with a rectifier, a regulator, or other appropriate circuit (for example, an overcurrent protection circuit). These circuits are obvious to those skilled in the art and are not described in the figure.

  The light bulb further includes at least one lamp panel 30 and a support column 40. The lampboard 30 can be circular, polygonal, or other shapes as shown. At the periphery of the lamp panel 30, two or more light emitting diodes 31 facing each other are provided at intervals. “Look back at each other” means that the front surface (light-emitting surface) of the light emitting diode 31 faces the centrifugal direction of the lamp panel 30 and the back surfaces face each other. As shown in FIG. 1b (of which the dotted line represents the emission range of the light rays), it can be seen that the emitted light rays of the light emitting diodes 31 collectively form an illumination range in almost all directions, thereby causing the light emission of the light emitting diodes. The problem of directional localization can be solved. Therefore, as the number of light emitting diodes 31 employed by each lamp panel 30 increases, the distance between the light emitting diodes 31 decreases, the omnidirectionality of the illumination range of the bulb increases, and the brightness also increases. Referring to FIG. 2 simultaneously, one or more lamp panels 30 can be employed to further improve the brightness of the bulb.

  As shown in FIG. 2, the support column 40 extends into the lamp body 10 from the end body 20 and connects at least two lamp panels 30 at intervals. In an embodiment in which at least two lamp panels 30 are used, in order to save the amount of light emitting diodes 31 used, the light emitting diodes 31 of two adjacent lamp panels 30 are arranged in an alternating manner (that is, two in the vertical direction Adjacent light-emitting diodes 31 are not arranged at the same position), and as shown in FIG. 2, the light-emitting diodes 31 achieve a uniform distribution in a three-dimensional space, efficiently increase the degree of illumination, and avoid the inconvenience of overlapping irradiation ranges To do.

  The support column 40 has an electric conduction function in addition to the function of fixing the lamp panel 30. Each lamp board 30 has at least a circuit, and supplies electricity to the light emitting diode 31 thereon to operate it. The support column 40 also has a conductive mechanism, and connects the circuit of the end body 20 and the circuit of each lamp panel 30. For those skilled in the art, the circuit and the conduction mechanism are obvious and will not be described here.

In the present invention, preferred embodiments have been disclosed as described above, but these are not intended to limit the present invention in any way, and anyone who is familiar with the technology has an equivalent scope that does not depart from the spirit and scope of the present invention. Of course, various fluctuations and hydration colors can be added.
